Describes a chemistry program in which experiments are performed for students in grades one to three. The experiments use only materials and apparatus found in the average home so they can be reported by teachers or parents. Students become involved in the program by asking questions and making predictions. (JN)

Describes an interdisciplinary chemistry course at the New Jersey Institute of Technology (NJIT) in which at least one quarter of the time is devoted to materials science. Includes information on course content, laboratory work, and assessment of student performance on chemistry and materials science topics. (JN)

Outlines a simple method which shows the relation between work done in accelerating a mass and the resulting velocity of the mass. Equipment used includes a rubber ball, ramp of lumber, graph-chart, stopwatch, and hand calculator. (DH)

Discusses modifications and special equipment needed by wheelchair-bound students for 33 common freshman physics experiments. Physical adjustments, individual needs, and personnel are addressed, with emphasis on building a rapport to learn what a student can and cannot do. A list of modifications for specific experiments (by topic) is included.…

Reviews three experiments which can be used to introduce microscale techniques. Highlights the benefits and advantages of having undergraduate students prepare and purify derivatives on the small scale. (ML)

Deals with a diffraction experiment using wrapping paper. Provides a magnified picture of the paper, a diffraction diagram, and some instructional information. (YP)

The evolution of the University of Wisconsin at Madison Interpersonal Skill Training and Research Project, which has produced 18 dissertations based on true experiments in direct social work practice, is described. Guidelines for constructing a true experiment as a dissertation are outlined. (MSE)

Provides background information on the equipment and knowledge necessary to do an astronomy activity on the earth's rotation. Details an activity in which students can measure the rotation of the earth using a camera and the stars. (CW)

Describes how short-term laboratory projects were used to teach population and community ecology to undergraduate environmental science students. Directed students to formulate and implement their own hypotheses and experimental designs. Uses questionnaire results and written reports to assess the contribution of the course to student…

Provides information appropriate for introductory lectures on photoelectric effects in membranes. Describes the apparatus and supplies required for laboratory exercises. Outlines typical laboratory exercises. Identifies the chromophores known to induce photoelectric effects. Concludes that this topic can provide useful subjects for undergraduate…

Examines the usefulness of cyclic voltammetry to the determination of a complex compound's stoichiometry. Discusses the experimental design, laboratory equipment, and results. (CW)

Presents several teaching suggestions associated with the raising of monarch butterflies in classrooms. Emphasizes how this endeavor can be used to enhance the use of science process skills. (TW)

Describes two complementary laboratory exercises that use the glass fiber assay to assess receptor specificity and hormone binding affinity in rat liver cytoplasmic extracts. Details the methods, materials and protocol of the experiments. Discusses the basic concepts illustrated and the feasibility of using the experiments at the undergraduate…

Describes an experiment to discover the topology of plasma membrane aminophospholipids (phosphatidylethanolamine and phosphatidylserine) using whole platelets and trinitrobenzene sulfonate (TNBS) as a probe. Reports changes in phospholipid distribution during platelet activation with simultaneous action of thrombia and collagen. Details the…

Describes how, using an overhead projector (OHP) and a transparent roll of acetate film, it is possible to demonstrate: (1) travelling waves; (2) standing waves; and (3) phase and group velocity applied to waves. The set-ups provide a way to demonstrate features which are normally difficult to visualize and understand. (JN)
